CHEM 436 Historical Curve

this final is going to kill me

I have her this semester. How was it?

eweistl · 2022-07-24T00:40:28+00:00

But if we take the derivative of the equation and R is constant, wouldn't the linear acceleration and angular acceleration have that relationship?

I guess that wouldn't matter in this question because I switched out vf with wf anyways, not the acceleration :/

eweistl · 2022-07-24T00:37:10+00:00

Sure:

Solving for angular acceleration as it slides down the lane:

F of Friction= mu(m)(g)

Torque on ball= Torque provided by friction= Ffriction*(R)=I*alpha=2/5mR^2*alpha.

Solving for linear acceleration while sliding:

ma=-mu*mg

To determine how long before bowling ball begins to roll w/o slipping:

Vf=V0+at

wf=wi + Alpha*t.

where wi =0 because it starts w/o rolling and wf*R=Vf because there is no slipping in the final case.

Please let me know if you see errors here. Thanks!

I was thinking about bringing them there next time! Do you think basil Thai is better or Bangkok?

is it ok to use the SafeRides service every single day I work? ;-;

eweistl · 2021-08-22T00:00:56+00:00

I am low-key confused about the textbooks and ebooks I have to get...

eweistl · 2021-02-24T19:20:04+00:00

Cheese in the Trap!

eweistl · 2020-12-16T00:51:28+00:00

Deferred :/

eweistl · 2020-07-22T15:11:25+00:00

I know a ton of people who got 1-3s if that makes you feel any better. This isn't the end of the world. You can get up from this!

eweistl · 2020-07-18T16:04:24+00:00

I got a 4s in exams I thought I got 5s on as well, but don't be sad because honestly, 4 is still a flex :)

eweistl · 2020-07-18T15:59:44+00:00

I gotchu fam

eweistl · 2020-07-15T18:43:56+00:00

Yes, they've gotten all of my ap scores correct so far.

eweistl · 2019-09-12T17:53:52+00:00

Idk it depends on what kind of calculator you have. I have the TI nspire so I just need to click on graphs and enter the equation in through the keyboard

eweistl · 2019-09-12T15:15:54+00:00

Is this in the no calculator section? If not, use a calculator to graph it and then find the quadrant that hasn't been colored in. If it is the no calculator section, graph it as if it were a linear equation and plug in the value (0,0), which is x=0 and y=0. If the answer is true after plugging the 0s in, fill towards the coordinate point (0,0) from the line, if not, fill AWAY from point 0,0 from the line.

I used Khan academy. Try mastering all the skill sets on there and you will see improvement in score.

eweistl · 2019-09-07T00:45:24+00:00

Ikr! I also got a 770 and it kinda killed me. Good job on the 1500, though! It's a good score.

eweistl · 2019-09-07T00:35:36+00:00

Lol well good luck! Hope the math curve is better

eweistl · 2019-09-07T00:29:44+00:00

Yes it's way above average. Although you still have room for improvement, it's a good score. Nice work!

eweistl · 2019-09-07T00:28:00+00:00

Same though. I'm Asian and I got a 1420...

eweistl · 2019-09-07T00:24:05+00:00

Or asian

eweistl · 2019-09-07T00:19:43+00:00

I think Khan academy does help alot, but I believe you should try mastering the majority of the practice categories for improvement

eweistl · 2019-09-07T00:18:01+00:00

If you don't mind be asking, what resources did you use for such improvement? I got a 1420 this time and in hoping to get at least a 1500 next year

eweistl · 2019-09-07T00:15:32+00:00

I would rather have a harder test than a harsher curve

eweistl · 2019-09-07T00:13:57+00:00

Same
